British Gas has appointed brand experience agency BEcause to help with its sponsorship of the RAC Future Car Challenge.
The annual race from Brighton to London features a range of electric cars and the winner is the vehicle which uses the least energy to make the journey.
BEcause's brief is to create an exhibition stand in a solar-panelled container at the ceremonial finish on Regent Street.
Over 500,000 people are expected to attend the event on Saturday.
